Which of the following hormones controls the functioning of adrenal cortex ?

Options

A. TSH
B. FSH
C. ACTH
D. LH

Answer

To solve the question "Which of the following hormones controls the functioning of the adrenal cortex?" let's break it down step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Option 1: TSH (Thyroid Stimulating Hormone)
- Option 2: FSH (Follicle Stimulating Hormone)
- Option 3: ACTH (Adrenocorticotropic Hormone)
- Option 4: LH (Luteinizing Hormone)

2. **Understand the Function of Each Hormone**:
- **TSH**: This hormone stimulates the thyroid gland to produce thyroid hormones (thyroxin and triiodothyronine) which regulate metabolism in the body. It does not affect the adrenal cortex.
- **FSH**: This hormone is involved in the regulation of the reproductive processes and the development of gametes (sperm and eggs). It is not related to the adrenal cortex.
- **ACTH**: This hormone is produced by the anterior pituitary gland and specifically stimulates the adrenal cortex to produce cortisol, a vital hormone for metabolism and stress response.
- **LH**: This hormone also plays a role in the reproductive system, stimulating ovulation in females and testosterone production in males. It does not influence the adrenal cortex.

3. **Determine the Correct Answer**:
- Among the options, ACTH is the only hormone that directly controls the functioning of the adrenal cortex by stimulating it to produce cortisol. Therefore, the correct answer is **ACTH**.

4. **Conclusion**: The hormone that controls the functioning of the adrenal cortex is **ACTH (Adrenocorticotropic Hormone)**.

### Final Answer:
**ACTH (Adrenocorticotropic Hormone)** controls the functioning of the adrenal cortex.
